SodaStream Bottle Lifespan

The SodaStream 1/2L PET Carbonating Bottles in green/red each have a 2-year lifespan from when you first start using them. The final expiration date, when the cap can no longer maintain carbonation, is stamped on the bottom for easy reference. The unique hermetic seal on the bottles is highly effective at keeping drinks fizzy. The bottles should be only washed by hand. This carbonating bottle twinpack from SodaStream is perfect for keeping soda and sparkling water cold and bubbly in the refrigerator.
